Rearing Chrysomya megacephala on artificial diets composed of varying concentrations of albumin

Abstract

Larvae of the blowfly Chrysomya megacephala were reared on an artificial diet composed of five different concentrations of albumin (2, 4, 6, 8 and 10%) and the control group was fed on putrid bovine meat. No larvae developed in the 2 and 10% albumin concentrations. The period from newly hatched larvae to adults reared on 4, 6 and 8% albumin was 13.1, 13.1 and 13.6 days, respectively, whereas for the control group, it was 11.2 days. Concentrations of 4, 6 and 8% albumin proved viabile for larval periods of 29.3, 44.0 and 57.3%, respectively, whereas for the control group, it was 77.3%. Pupal viability was 77.3, 36.4 and 83.7%, while for the control group, it was 84.5%; the newly hatched larvae to adult viability was 21.3, 16.0 and 48.0%, respectively, and for the control group, it was 65.3%.O presente trabalho teve como objetivo avaliar o desenvolvimento pós-embrionário de Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) em dietas artificiais à base de albumina nas concentrações de 2%, 4%, 6%, 8% e 10% de albumina e como controle foi utilizada a carne bovina moída putrefata. Não houve desenvolvimento nas dietas de concentração 2% e 10% de albumina. A duração do período de larva a adulto foi 13,1; 13,1 e 13,6 dias, respectivamente, e a do controle foi de 11,2 dias. As dietas artificiais nas concentrações 4, 6 e 8% de albumina apresentaram viabilidades larvais de 29,3; 44,0 e 57,3%, respectivamente e o controle 77,3%; as viabilidades de pupa foram 77,3; 36,4 e 83,7% e o controle 84,5%, respectivamente; as viabilidades de larva a adulto foram 21,3; 16,0 e 48,0% e o controle foi de 65,3%, respectivamente.
